Are fluctuations in the stock market tied to a dopamine cycle in the human brain

Observations of a small and informal study are presented proposing a 40-day-long dopamine cycle in the human brain. This cycle has 10 days of low dopamine followed by 10 days of high dopamine (resembling a pulse shape), followed by 20 days of normal dopamine. There are nine 40-day-long cycles each year, starting and ending at the winter solstice. The model presents nine “buy low,” and 35 days later, nine corresponding “sell high” dates, that match market drops every year compared to historical and present S&P 500 stock market data. The study speculates that the subconscious mind drives anticipatory anxiety, five days before the start of the dopamine drop, that occurs every 40 days to backup memories to long term memory in the human brain.
